Geotagging your photos? Old hat -- Neurowear wants to geotag your mood. The folks that brought animated cat ears to the human race is now using NeuroSky's brainwave-reading headgear to suss out your emotional state and share it with your friends. We dropped in on the group at Tokyo Game Show to take a look at an early prototype. After strapping a familiar Mindwave mobile headset to this editor's skull, a companion iPhone app sprung to life, reading off relaxation levels and assigning cartoon faces to the user's mood. The reading could then be recorded on a map, tagging how the user felt at a given location and time and allowing them to share that information with their friends. Had a great time at a new coffee shop? Now you can prove it, and encourage your social contacts to join you. It's an interesting idea, but its still a long way from hitting the app store -- the demo we were given was only a concept app, and the geotagging portion of the demonstration was simulated. It may be awhile before you can tweet your feelings directly. Need another way to express yourself? Don't worry -- Nerosky is adding a brainwave controlled tail, dubbed Shippo, to its line of cranium controlled animal parts. Check it out (as well as our quick neurotagging demo) after the break.

Sony's second generation 3D visor didn't make a big splash back at IFA, but the HMZ-T2 certainly has a pigeonhole at Tokyo's premier gaming event. In addition to the headset's substitutional reality prototype, the standard model stakes claim to almost a fifth of PlayStation's demo area. With all the local buzz, we decided to weigh in on how the $900 headgear shapes up as a gaming display. The answer? Heavily. Out of necessity, the HMZ-T2 crams the majority of its hardware in front of the users eyeballs, bearing most of its weight on the nose. Over extended gaming sessions, we could see this becoming uncomfortable -- and indeed, in our short time with the device we found our neck relaxing, begging to give in to the weight of the device. As silly as hung-head gaming might appear, however, the visual effect certainly does the trick -- creating the illusion of a large 3D television 4-6 feet in front of the user. It didn't add anything to Hot Shots Golf 6 in terms of gameplay or experience, but it certainly comes in a more compact form than a full size television. The fancy headgear could surely be a boon for gamers living in a tight space, but folks with room (and cash) to spare are probably better off with a proper flat screen. On the other hand, visors are way more futuristic looking. Don't believe us? See us get our Geordi La Forge on after the break.

After the new PS3s had their moment in the spotlight at Sony's pre-TGS press event, the company also announced color variants for the PS Vita. We weren't able to fondle the pair just yet, the key difference is quite obvious: "cosmic red" and "sapphire blue" exteriors. Both of the new models share the same glossy coating as the original model, so they're sure to attract your fingerprints. These two round out the paint schemes at four when you include the "crystal white" version that's already been unveiled. While we snag a spot in line for a hands-on at the Sony booth, take a peek at the gallery that follows for a quick look at the duo.Gallery-165877

Just after their pre-TGS announcement, we were able to snag a closer look at Sony's new slimmed-down PlayStation 3 consoles. While we weren't able to put our grubby mitts on the pair, we did get a peek at some of the exterior differences. Aside from the obvious color variations (at least in the white model that's definitely headed for Japan), the first change that immediately jumps out is the absence of the visible disc slot on the console's front. We surmise that discs now load via a sliding tray mechanism of some sort -- a feature that we'll definitely take a closer look at when we grab a full hands-on on the show floor. There's also a grooved design up top, which makes a departure from the smooth casing from the previous models. From the display we took a gander at, an attachable base is included to secure the unit when used vertically. Want a closer look for yourself? Dive in to the gallery below to do just that.

Move over HTC -- both Sharp and Fujitsu are joining Sony's PlayStation Certified program, allowing games in the PlayStation Mobile marketplace to be purchased and played on various portable devices from the two hardware manufacturers. In Fujitsu's case, its ARROW series of smartphones and tablets will carry the PlayStation Mobile titles, while Sharp isn't getting specific just yet.

Beyond the partnership announcement, Sony's PlayStation Mobile SDK comes out of beta this November and becomes available for any developer. Licences cost $100/year, and the SDK becomes available on a region-by-region basis starting with Japan, the United States, Canada, United Kingdom, France, Germany, Italy, Spain, Australia, Hong Kong and Taiwan, allowing for cross platform development on PlayStation Certified devices and the Vita.

Update: The PlayStation Mobile store will launch on October 3rd in nine countries, including Japan, the US, Canada and the UK, carrying 30 titles on the opening day, with more coming as they roll off the production line.

Sony's PS3 / Vita cross-buy program might not be as simple as "buy one, get one" after all. Taking the stage at its pre-TGS press event, Sony announced a new Hot Shots Golf game as one of the program's first adopters -- citing a price reduction, rather then a free game, for users who pick up either the PS3 / Vita version of the title. In contrast, Sony stated at Gamescom that buyers of PlayStation All-Stars Battle Royale and Ratchet & Clank: Full Frontal Assault would receive a second copy of the game for free upon purchase, indicating that cross-buy discounts may vary from title to title. Remember kids: just because you bought it once, doesn't mean you won't have to buy it again.

Just because Sony's focus during the Tokyo Game Show is on its two newest consoles, the Vita and the PlayStation 3, doesn't mean the company's forgotten about the PlayStation Portable. During its press conference this evening, Sony dropped ¥3,000 (about $40) from the ¥16,800 (about $215) base price of the PSP in Japan, putting the console at ¥13,800 (about $176). It's unclear if any price drop will affect North American or European consumers, but we'll update as we find out more.

If Sony's handheld wonder lacks the visual pop your discerning sense of style craves, you're in luck: the Vita's getting a new look. Sony teased a rainbow of colorful handhelds at TGS last year, but opted to launch the handheld in a classic black facade and added a white version back at E3 that is slated for October. Now, the outfit has revealed two new options: "cosmic red" and "sapphire blue." The details on pricing and availability are still coming in, but the pair will hit shelves in Japan on November 15th. In the meantime we'll offer details for US and Europe as soon as they become available.Gallery-165866

A few years ago, Sony pulled the curtain back on a slimmed-down version of its PlayStation 3, and yet another Japan-only version since then. Today at the company's pre-Tokyo Game Show press event, the latest rumoredredesign to the PS3 was announced. The new duo gets even smaller in stature and will arrive in stores with both black and white offerings, available in 250GB and 500GB models. The "charcoal black" option has a September 25th launch date for the 250GB bundle (with Uncharted 3: Drake's Deception "Game of the Year Edition") and a $269.99 price tag, while the "classic white" model arrives on November 22 (at least in Japan -- this is a TGS presser after all). For those looking for more storage space, the 500GB, charcoal-only option will be available on October 30th in conjunction with the Assassin's Creed III release -- no word on pricing just yet, though. Sony Computer Entertainment CEO Andrew House introduced the new model, calling it 50 percent smaller than the original (rather large) PS3, and 25 percent smaller than the previous slimmed-down version.

This week Japan's capital city welcomes gamers from around the globe for some show and tell with the country's finest at TGS. As for us, we're particularly anxious to see what Sony may have in store. Will we see anotherPS3 redesign? Perhaps some buzz about it's next-gen console? Will we see some energized color options for the PS Vita? We're eager to find out. Worried you're too far away to be in the loop with the happenings here? Fret not! We've got you covered on all of the proceedings at Makuhari Messe, so keep your peepers locked here for all of the latest news over the next few days.
